264 Jayaraj et al. – A Model to Differentiate Cynopterus brachyotis Forms on Wilks’ lambda (Table 3), and 6 characters (GBPL, M3L, M3W, TVL, D3P2L, and RL; Table 4) were generated from the stepwise procedure. The characters with the highest weight on function 1 were RL (0.957) and M3L (0.506), whereas M3L (3.912) and M3W (-3.454) had the highest discriminant loadings. All 6 characters determined by the stepwise procedure produced a discriminant function with an accuracy rate of 100% (see accuracy rates, Table 5). For analysis of only external morphological characters, the stepwise method identified a discriminant function (Function 1) that was statistically significant (Table 6) with 4 characters (TVL, D3P1L, D3MCL, and RL; Table 7) generated from the stepwise procedure. The character with the highest weight and loading was RL (weight = 1.240; loading = 0.706), while D3MCL (-0.731) had the 2nd-highest weight. All 4 characters determined by the stepwise procedure produced a discriminant function with an accuracy rate of 96.8% (see accuracy rates, Table 8).

<strong>Zoological</strong> <strong>Studies</strong> 51(2): 259-271 (2012) 265 (Fig. 4) showed that C. brachyotis and C. cf. brachyotis Forest formed distinct groups, whereas the histogram of the discriminant scores of the discriminant function for only external morphological characters (Fig. 5) showed some misclassifications (2 individuals).
